Show transcript
A shadow is a dark shape formed when light is stopped or blocked by an object. Opaque objects do not allow light to travel through them. Translucent objects let some light through. A shadow can be different sizes depending on the distance of the object from the light source. Shadows are dark where the light has been blocked and they do not show the features of the object. Shadows of objects are not the same as reflections of them.
